FIG 2. Comparisons of qualitative rCVR with quantitative rCVR (%Hem) calculated by using the IMP autoradiographic method. Significant correlation was observed between these two values. A plot of the relationship between these two values revealed four groups of results: 1) those with reduced rCVR (true-positive), 2) those in which only the quantitative method identified reduced rCVR (false-negative), 3) those without reduced rCVR (true-negative), and 4) those considered reduced rCVR only by the qualitative method (false-positive). Dashed horizontal and vertical lines denote the mean - 2 SDs of the rCVR values obtained in healthy volunteers by using the quantitative method or the qualitative method.
A, AIHem change.
B, FIHem-Cbl change.
